Title: Method for text communication between terminals, in particular telephone terminals, connected to communications switching systems
Inventor: JUNG WOLFGANG
IPC: H04M3/533
Filed: 1988-11-30
Abstract: Using a simple operating procedure from subscriber stations, the text communication method is intended to enable the compilation of a text which can be forwarded not only to the respective callers but also to specifically selected subscriber stations. This text communication is intended to be possible irrespective of the connection condition, even when a call is in progress. A text communication device which can be dialled up from the subscriber stations is connected to a communications switching system. Various raw texts, which are selected by means of operating procedures and completed by data inputs, are available to the subscriber stations. Buffer memories and subscriber text memories are also available in which references to the individual components of the text which is to be despatched are stored. Depending on which areas within a subscriber text memory are occupied, a complete text message is compiled by a text control device on the basis of the stored information and is transmitted either to the respective callers or to pre-defined subscriber stations. The operating procedures for text compilation are relatively simple and require little time, since every individual letter does not have to be entered. If raw texts simply need to be supplemented by data comprising digits, no alphanumeric keyboard needs to be provided on the terminal concerned. With ... Original abstract incomplete.

Patent DE-3907328-A1 (DE)
Title: Solar compass
Inventor: HAMANN ULRICH
IPC: G04B49/02
Filed: 1989-03-03
Abstract: This solar compass is used for exact determination of the celestial direction from the position of the sun at that time. Unlike magnetic compasses, it cannot be deflected from the correct reading by magnetic, electrical or other influences, by iron, steel or the like in its surroundings and has no pole-dependent declination. It consists of a simple disc with a 24-hour dial, on which a moving pointer is centrally fixed. If this pointer is set to the corresponding time of day and then pointed at the sun, the 24 mark of the dial (labelled N) will point exactly northwards at all times and at all locations. The simplicity of production and use will greatly encourage the popularity of this device. If this solar compass is set up pointing northwards, it can also be used as a sundial made in all possible sizes and of all possible materials. The pointer needs then only to be pointed at the sun and then simultaneously indicates the time of day on the dial.
Patent DE-3909807-A1 (DE)
Title: Remote control
Inventor: THOMPSON DAVID RICHARD
IPC: H02J13/00
Filed: 1989-03-24
Abstract: In network line carrier transmission and reception for the purposes of remote control, a slave receiver counts carrier cycles in a time window near to a zero passage of a supply line. The receiver uses discrete components (1, 2, 3) and a microprocessor. The discrete components form an input filter (1), a limiting pre-amplifier (2), a demodulator and noise filter (3) and devices to determine the zero passage points (4). A capacitor is charged and discharged, depending on the rate of occurrence of carrier cycles, in order to generate a binary signal which is dependent on the digital value present on the carrier. By measuring the time span in which the binary signal is located in the window in one of its states, the microprocessor determines whether the signal is the result of noise or not. <IMAGE>

Title: Cleaning device for spectacle lenses - comprises pen in which cleaning fluid moves from lower storage tank to upper dirt pick=up chamber
Inventor: VOELKENING ECKEHARD
IPC: G02C13/00
Filed: 1990-08-24
Abstract: The device takes the form of a pen with an applicable closure cap (7). The cleaning surface on the ehad of the pen extends outwards, and encloses a pump volume (4) which when the closure cap is removed automatically enlarges, and then reduces in size with the cap is re-applied. The pump volume is connected by a tube with a storage tank in the pen to receive cleaning fluid. The connecting tube is blocked in the normal state by a check valve which then only permits flow towards the pump volume when its is affected by a suction pressure as the result of enlargement of the pump volume. In the closure cap is a dirt pick-up chamber (8) which with an open pressure wall locates against the pump volume when the closure cap is applied to the pen. This causes the pump volume to be reduced. With the cap applied, the dirt pick-up chamber is in permanent connection with the atmosphere via at least one evapn aperture (10). USE - Principally for cleaning spectacle lenses, but also suitable for helmet vizors, car mirrors, binoculars, camera lenses, etc.
